Chapter 5 : ANIMATION
Animation involves creating the illusion of movement by displaying a series of images in rapid succession. The document discusses different types of animation including cel animation, which uses clear celluloid sheets drawn by hand, and computer animation, which automates parts of the animation process. It also covers file formats for animation and best practices for creating successful animations, such as using animation sparingly and compressing files for web display.

- 11. Type of Animation:Typeof Animation: Cel AnimationCel Animation • Cel animation is a technique in which a series of progressively different graphics are used on each frame of movie film. • The term "cel" is derived from the clear celluloid sheets that were used for drawing each frame. • Cel animation begins with keyframes.
- 12. Type of Animation:Typeof Animation: Cel AnimationCel Animation • Keyframes refer to the first and the last frame of an action. • The frames in between the keyframes are drawn in the tweening process. • Tweening depicts the action that takes place between keyframes. • Tweening is followed by the pencil test.
